Fracking gets the green light from the coalition

Energy Secretary Ed Davey says drilling for shale gas can resume subject to controls "to mitigate the risks of seismic activity".

Energy Secretary Ed Davey has just given the go-ahead for fracking, the technique used to extract shale gas, to resume in the UK, subject to controls "to mitigate the risks of seismic activity". Exploration was previously halted after test-drilling by the company Cuadrilla caused two minor earthquakes in Lancashire.

Davey said: "Shale gas represents a promising new potential energy resource for the UK. It could contribute significantly to our energy security, reducing our reliance on imported gas, as we move to a low-carbon economy. My decision is based on the evidence. It comes after detailed study of the latest scientific research available and advice from leading experts in the field."

However, he cautioned that "We are still in the very early stages of shale gas exploration in the UK and it is likely to develop slowly. It is essential that its development should not come at the expense of local communities or the environment. Fracking must be safe and the public must be confident that it is safe."

New controls to limit seismic risk include:

  • A prior review before fracking begins must be carried out to assess seismic risk and the existence of faults;
  • A fracking plan must be submitted to DECC showing how seismic risks will be addressed;
  • Seismic monitoring must be carried out before, during and after fracking;
  •  A new traffic light system to categorise seismic activity and direct appropriate responses. A trigger mechanism will stop fracking operations in certain conditions.

In addition, Davey announced that he was commissioning a study of the possible effects of shale gas development on greenhouse gas emissions and climate change, although green campaigners are questioning why this was not held before the latest annoucement.

Greenpeace's energy campaigner Leila Deen said: "George Osborne's dream of building Dallas in Lancashire is dangerous fantasy. He is not JR Ewing and this is not the US. Energy analysts agree the UK cannot replicate the American experience of fracking, and that shale gas will do little or nothing to lower bills. Pinning the UK's energy hopes on an unsubstantiated, polluting fuel is a massive gamble and consumers and the climate will end up paying the price."

It became clear that ministers were preparing to give fracking the green light after George Osborne's Autumn Statement promised tax incentives for shale gas industry and announced the establishment of the "Office for Unconventional Gas".

Labour has said that fracking should only go ahead "if it is shown to be safe and environmentally sound" and that it will "look carefully" at the government's proposals. Shadow energy secretary Caroline Flint added: "The idea that this form of gas extraction can have the same impact here in the UK as it has had on gas prices in the United States is considered wishful thinking by most experts."

We'll have more response to the announcement later on The Staggers.

The deafening killer - why noise will be the next great pollution scandal

A growing body of evidence shows that noise can have serious health impacts too. 

Our cities are being poisoned by a toxin that surrounds us day and night. It eats away at our brains, hurts our hearts, clutches at our sleep, and gnaws at the quality of our daily lives.

Hardly a silent killer, it gets short shrift compared to the well-publicised terrors of air pollution and sugars food. It is the dull, thumping, stultifying drum-beat of perpetual noise.

The score that accompanies city life is brutal and constant. It disrupts the everyday: The coffee break ruined by the screech of a line of double decker buses braking at the lights. The lawyer’s conference call broken by drilling as she makes her way to the office. The writer’s struggle to find a quiet corner to pen his latest article.

For city-dwellers, it’s all-consuming and impossible to avoid. Construction, traffic, the whirring of machinery, the neighbour’s stereo. Even at home, the beeps and buzzes made by washing machines, fridges, and phones all serve to distract and unsettle.

But the never-ending noisiness of city life is far more than a problem of aesthetics. A growing body of evidence shows that noise can have serious health impacts too. Recent studies have linked noise pollution to hearing loss, sleep deprivation, hypertension, heart disease, brain development, and even increased risk of dementia.

One research team compared families living on different stories of the same building in Manhattan to isolate the impact of noise on health and education. They found children in lower, noisier floors were worse at reading than their higher-up peers, an effect that was most pronounced for children who had lived in the building for longest.

Those studies have been replicated for the impact of aircraft noise with similar results. Not only does noise cause higher blood pressure and worsens quality of sleep, it also stymies pupils trying to concentrate in class.

As with many forms of pollution, the poorest are typically the hardest hit. The worst-off in any city often live by busy roads in poorly-insulated houses or flats, cheek by jowl with packed-in neighbours.

The US Department of Transport recently mapped road and aircraft noise across the United States. Predictably, the loudest areas overlapped with some of the country’s most deprived. Those included the south side of Atlanta and the lowest-income areas of LA and Seattle.

Yet as noise pollution grows in line with road and air traffic and rising urban density, public policy has turned a blind eye.

Council noise response services, formally a 24-hour defence against neighbourly disputes, have fallen victim to local government cuts. Decisions on airport expansion and road development pay scant regard to their audible impact. Political platforms remain silent on the loudest poison.

This is odd at a time when we have never had more tools at our disposal to deal with the issue. Electric Vehicles are practically noise-less, yet noise rarely features in the arguments for their adoption. Just replacing today’s bus fleet would transform city centres; doing the same for taxis and trucks would amount to a revolution.

Vehicles are just the start. Millions were spent on a programme of “Warm Homes”; what about “Quiet Homes”? How did we value the noise impact in the decision to build a third runway at Heathrow, and how do we compensate people now that it’s going ahead?

Construction is a major driver of decibels. Should builders compensate “noise victims” for over-drilling? Or could regulation push equipment manufacturers to find new ways to dampen the sound of their kit?

Of course, none of this addresses the noise pollution we impose on ourselves. The bars and clubs we choose to visit or the music we stick in our ears. Whether pumping dance tracks in spin classes or indie rock in trendy coffee shops, people’s desire to compensate for bad noise out there by playing louder noise in here is hard to control for.

The Clean Air Act of 1956 heralded a new era of city life, one where smog and grime gave way to clear skies and clearer lungs. That fight still goes on today.

But some day, we will turn our attention to our clogged-up airwaves. The decibels will fall. #Twitter will give way to twitter. And every now and again, as we step from our homes into city life, we may just hear the sweetest sound of all. Silence.
